Pest Animal Control

Lord Howe Island is a World Heritage Area of global environmental significance and it is important to effectively manage it's world-renowned natural values. Introduced pest species can seriously impact upon the biodiversity of the Island by modifying species richness, abundance, and ecosystem function. They can also have significant impacts on the economic and social values of neighbouring areas.

During the 1980's and 1990's the Lord Howe Island Board successfully eradicated feral cats, pigs and goats from the Island.

Recently a draft eradication plan for Ship Rats and Mice and a strategy for the eradication of African Big-headed Ants have been prepared. Refer to the Plans area of this website for details.

Several other invasive pest species occur on the Island such as Mallard x Pacific Black Duck hybrids (Anas supercilliosa x Anas platyrhynchos) and Feral Pigeons (Columba livia). Control strategies are in place for these species as they have the ability to recolonise the Island.

Other feral populations occurring on Lord Howe Island include:

  • Common Starling (Sturnus vulgaris)
  • Masked Owl (Tyto novaehollandiae)
  • Blackbird (Turdus merula)
  • Song Thrush (Turdus philomelos)
  • Bleating Tree frog (Litoria dentate)
  • Grass Skink (Lampropholis delicata)
  • Eastern Snake-necked Turtle (Chelodina longicollis)
